Luke Wright said he'd didn't want to be known as a one-day specialist after scoring a first-class best 155 not out for county champions Sussex against MCC in the traditional opening fixture of the English cricket season here at Lord's on Saturday,

At stumps, on the third day of this four-day match, Sussex were 474 for five in their second innings, a lead of 440.

Wright, 23, has played five one-day internationals and seven Twenty20s since making his 50-over debut for England against India at The Oval in September.

But he is wary of being dismissed as a mere short-order hitter and, in a match where young players can impress the selectors, an innings which easily beat his previous first-class best of 100 against Loughborough University four years ago was testimony to his ambitions.

"I just want to try to build on what has happened in the winter and kick on again this summer - this is a good start," said Wright, also a lively seamer, who came to prominence last season on the back of his Twenty20 exploits.

"It is time to concentrate improving my form in Championship-mode, try to break in as a top-six batter and be a true all-rounder.

"Just to be with England is so special but once you get a taste you want to keep playing," added Wright, whose innings against MCC has so far lasted 185 balls with three sixes and 21 fours.

Wright had earlier made his mark in this match by bouncing England batsman Owais Shah into error on Saturday. He then felled Steve Kirby, who like Wright began his career at Leicestershire, with a short ball that knocked the Gloucestershire seamer unconscious.

Kirby passed out again in the pavilion but, after a night in a nearby hospital, was sent home to rest Saturday.

"I have seen Kirbs, we've had a little hug and he's fine about it," Wright added. "I am sure I will get a few back at some point.

"I know him really well, since being a kid, so I am sure we will have a drink and a laugh about it at some point now he's okay.

"Once he got off the pitch I thought that was it but to see him in the changing room - and him being out on the floor - was obviously quite scary."

Sussex, bowled out for a meagre 171 in their first innings, saw opening batsman Chris Nash make 90 second time round while, at Saturday's close, all-rounder Robin Martin-Jenkins was 73 not out.
